AT-113 3 Volt Voltage Variable Absorptive Attenuator 40 dB, 0.5 - 2.0 GHz Features • • • • • • Single Positive Voltage Control: 0 to +3 Volts 40 dB Attenuation Range at 0.9 GHz ± 2 dB Linearity from BSL Low DC Power Consumption SOIC-8 Plastic Package Tape and Reel Packaging Available Rev. V6 Functional Schematic 3,4,5,6 8 7 6 5 Description M/A-COM’s AT-113 is a GaAs MMIC voltage variable absorptive attenuator in a low-cost SOIC 8lead surface mount plastic package. The AT-113 is ideally suited for use where linear attenuation fine tuning and very low power consumption are required. Typical applications include radio, cellular, GPS equipment and automatic gain/level control circuits. The AT-113 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased performance and reliability. 3. 4. 5. 6. VCC = +3 VDC @ 50 µA maximum. VC = 0 VDC to +3 VDC @ 50 µA maximum. External DC blocking capacitors are required on all RF ports. 39 pF used for data measurements. 1 2 3 4 Pin Configuration Ordering Information 1,2 Part Number AT-113 AT-113TR AT-113SMB Package Bulk Packaging Forward Tape and Reel Sample Board Pin No. 1 2 3 4 Function Ground Ground RF Port VCC Pin No. 5 6 7 8 Function VC Ground RF Port Ground 1.
